stillbattling brings up some good questions. I am not sure I would jump to the conclusion that parasites are to blame but they could be.
There have been studies shown that MS has relations to pathogenic organisms. There are studies showing that viruses could be the causative factor. HHV6 is a herpes based virus that has shown up in MS patients. https://hhv-6foundation.org/associated-conditions/hhv-6-multiple-sclerosis
Other researchers have shown that parasites could be to blame http://elizabethyarnell.com/effortlesseating/2012/07/could-multiple-sclerosis-be-a-parasitic-infection/
Supporting the body with quality nutrition is one of the better things that you can do. Unfortunately in modern civilization, we are exposed to a diet that is largely chemical based. These mutations in the food supply leads to increased stress in the body, makes the immune system work harder and so on.
Real nutrition feeds the cells of the body which makes it stronger. I would avoid processed foods and get rid of artificial sweetners and as many chemicals as you can including cosmetics that have harmful chemicals, hair sprays, fluoridated toothpaste, shampoos with toxic chemicals and so on. Chemicals put a stress on the immune system and detoxification.
Considering that one might not know which pathogen is responsible for your illness then I would use natural herbs that have potential to kill a multitude of pathogens.
Things that come to mind are fresh, raw garlic, black seed, turmeric, neem, coconut oil. Drink chai tea which has a multitude of natural antibiotics such as black pepper, cardamom, ginger, black tea and others. Hemp oil (not marijuana) has antibiotic properties and may well help stabilize the nervous system. Colloidal Silver
might be helpful as well since it can kill viruses and some bacteria.
